Poor OP, this kind of query inspires all kinds of responses.
I would think given the centuries upon centuries of human beings slapping scent onto themselves (hair, face, armpits, other body parts, with a variety of scented products, and let’s not leave out scented detergent or dryer sheets), there would be research on this, and serious research at that.
My mom always told me if people could smell you after you walked by, you were wearing too much. Perfume or cologne was meant to be smelled by people you intended to let very close to you. Tiny dabs in a few places, and then stop.
I made some very good friends in Italy when I was stationed there. If you have ever ridden a packed Italian bus after lunch on a hot day, you know they don’t mind natural body odors. One day after a glass of two of wine, these friends noted Americans smelled like chemicals - scent from soap, body wash, shampoo, conditioner, hair product, deodorant, body lotion, perfume, detergent, fabric softener, etc. It’s all in perspective.
